JBUTTON SETTING AND RIVE'IING MACHINE.

Application filed May 1, 1916.

T 0 all whom it may concern:

Be it known that T, FREDERICK E. STAN- LEY, a citizen of the United States, residing at Waterbury, in the county of New Haven and State'of Connecticut, have invented a certain new and useful Improvement in Button Setting and Riveting Machines, of which the following is a full, clear, and exact description.

This invention relates to that class of machines in Which a button, snap fastener socket, bur, washer, or other object of the same general character or type is to be set upon or affixed to an article, such as a garment, by means of a fastener such as a rivet, eyelet, or tack, and the object of the invention is to provide means to prevent the accidental movement of the holder which receives from the feeding mechanism the object to be set and presents it to the fastener and the means for unitingthe two and thereby precludes misplacement of the object in the holder and its untimely escape therefrom.

The invention consists of a reciprocating holder composed of partible fingers mounted to operatein conjunction with a setting plunger and adapted to receive the article to be set from the feeding mechanism and to hold it while being set, the fingers being supported in given position by a friction de vice duringcompletion of the cycleof movement of the plunger, as T will proceed'now to explain and finally claim.

Without thereby limiting the applicability or usefulness of the invention, T have herein shown it as applied to the machine forming the subject of my case filed April 17, 1916, Serial No. 91,771 (now Patent No. 1,192,239, dated July 2.5, 1916). f a

pended as it will be upon the descent of the plunger. Fig. 3 is a front view of the holder detached. Fig. 4 is a perspective view of the parts of the friction device.

The post, pedestal or standard 1, may be of any usual or approved construction to support the head and other parts of the machine; and the machine here selected for illustrating the invention is one designed for setting snap fasteners, and comprises the head 2, arched or hollowed out near its base to receive the push-finger 3, and the parts of its operating mechanism, as in the case referred to. On the head are mounted the hopper or magazine 4 to contain and feed the articles to be set, and the hopper or magazine 5 to contain and feed the fasteners. The hopper4 is provided with a chute or raceway 6 leading to the holder 7, and the particular form of holder herein shown comprises a pair of fingers 8 pivotally connected at 9 and held closed by a spring 10. This spring may be of any approved construction, but as herein shown it is a substantially inverted U-shaped wire, secured to the fingers by clipsll and having its free ends entered in holes in the sides of the fingers to keep them in place. The fingers are recessed part-way of their length on adjacent sides to form a slot 12, and this slot is utilizedfor the passage pf a screw 13 which is threaded into the face of the head 2 so as to secure the fingers to the head and permit a vertically reciprocating motion of the fingers. The tips 14: of the fingers are reverted so as to occupy a-position in the path of movement of the reciprocating setting plunger '15, and are formed in any suitable manner to receive the article to be set from the chute or raceway 6 and hold it while being acted upon by the plunger, which finally effects the separation or parting of the fingers upon thesetting of the article.

The plunger 15 is acted upon by a lever 16 pivoted at 17 on the head and connected by a connecting rod 18 with a crank shaft 19 suitably mounted upon the post 1, and carrying a band-wheel or other motion applying medium 20, so that the lever 16 may be given a walking-beam motion. The leading end or active end of the lever 16 is provided with a cross-pin 21 and the fingers are supplied with hooks-22which engage this pin. As the lever descends it carries with it the plunger 15 and the plunger then comes into contact with the article to be set which at that time is in the holder and carries it and the holder down a predetermined distance until the pressure of the plunger overcomes the tension of the spring 10 and separates or parts the constituent fingers of the holder and forces the article to be set out of the holder and onto its fastener. Upon completion of the act ofsetting, the lever 16 rises and its pin 21 coming into contact with the hooks'22 lifts the holder into position to receive another button or other object to be set. Between these movements, in the operation of prior machines of this general type, the holder will be unsupported and is liable to drop down and interfere more or less with the practical operation of the machine, and in order to overcome this objection, there is applied to the holder a friction device, see Fig. 4 for details, comprising a washer 23 placed next to the holder and a spring 24: surrounding a headed screw 25 which is passed through the washer 23 and the slot 12 in the holder and screwed into the head, the screw serving to regulate the tension of the spring so as to get suflicient pressure to bear upon the holder to retain it in desired position. On the down stroke of the plunger there is an interval when the pin 21 of the lever 16 has left the hooks 22 and consequently left the holder unsupported. It sometimes happens that the unsupported holder drops be fore the plunger has come into contact with the article in the holder, and if it drops far enough to hit the supporting stop screw hitherto used near the upper end of the slot in the holder, the impact is sufficient to disturb the article in the holder, so that the plunger does not register accurately with it, and indeed this impact is sometimes sufficient to jar the article out of the holder. By the use of the friction device 23, 24, 25, the holder is supported independently of the pin 21 and hooks 22 and with sufiicient firmness to permit the descending plunger to register with the article to be set and thus insure its proper delivery to the fastening medium. In the present arrangement the holder firmly holds the article to be set in proper alinement and contact with the plunger until the article is fastened or set, and there is no chance for its displacement.

Any suitable fastener feed may be used, modified as desired or necessary to suit the kind of fastener employed. The fastener feed herein shown includes the reciprocating push-finger 3 which is arranged horizontally above the anvil 26 and pivoted to an arm 27 which iseengaged by one member of a bell-crank lever whose other member 28 engages the slotted link 29 pivotally applied, as by bracket 30, to the, lever 16, and otherwise constructed and operating substantially as, shown in the case hereinabove referred to.

- As already stated, the holder construction may be modified to adapt it to the character of the article to be set, and the other parts of the machine will be likewise varied as the work may require.

What I claim is 1. In a button setting and riveting machine having feeding and setting mechanisms, a holder adapted to receive from the feeding mechanism the article to be set and to present it to the setting mechanism, means to reciprocate said holder, a separable connection between the holder and its reciprocating means operating during the setting movement of the machine to temporarily separate the holder from its reciprocating means, and a friction device applied to the holder for retaining said holder against accidental movement when separated from its reciprocating means and thereby preventing the displacement or dislocation of the article in the holder.

2. In a button setting and riveting machine having feeding and setting mechanisms, a reciprocating holder adapted to receive from the feeding mechanism the article to be set and to present it to the setting mechanism, ahead on which said holder is mounted, a reciprocating plunger in said head, a lever for operating sald plunger, means for partingly suspending the holder from said lever, and a spring friction device engaging the head and acting against the holder to prevent it from falling when parted from the lever prior to the engagement of the setting mechanism with the article in said holder.

3. In a button setting and riveting machine having feeding and setting mechanisms, a reciprocating holder adapted to-receive from the feeding mechanism the article to be set and to present it to the setting mechanism, and a friction device for retaining said holder against accidental displacement and movement during the operation of the machine, combined with a reciprocating plunger whose active end is in line with the older, a reciprocating lever for actuating the plunger to cause it to come into contact with the article in the holder, and means for suspending the holder from said lever during its reverse movement and permitting its parting therefrom in its setting stroke, said holder being supported by the friction device when parted from the lever, and movement of said holder being prevented by the friction device until such contact occurs.

4. In a button setting and riveting machine having feeding and setting mechanisms, a head supporting the button feeding mechanism, a reciprocating holder applied to said head and adapted to receive from the feeding mechanism the button to neonate be set and to present itto the setting mechanism, and a friction device engaging the head and holder for retaining said holder against accidental displacement and move- 5,-ment during the operation of the machine 10 place and tensioning the spring against said Washer and holder, combined with a reciprocating plunger whose active end is in line with the holder, a reciprocating lever for actuating the plunger to cause it to come into 15 contact with the article in the holder and.

having a transverse pin in its leading end, and fingers on the holder engaging said pin and adapted to part from it as the lever descends on its stroke and leave the holder unsupported save for the friction device which then actively holds the holder steady and prevents the accidental displacement of the button then in the holder.

In testimony whereof I have hereunto set my hand this 26th day of April A. D.
